SPECIFICATION forming part of Letters Patent No. 380,919, dated April10, 1888.

Application filed December 28, 1837.

T0 a-ZZ whom, it may concern.-

Be it known that I, ALBERT M. NASH, a citizen ofthe United States,residing at Owego, in the county of Tioga and State of New York,haveinvented certain new and useful Improvements in Flows; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawing,making a part of this specification, and to the letters and figures ofreference marked thereon.

The present invention has relation to that ments whereby the wheel anddraft-clevis can be conveniently lowered or raised without in providingmeans for attaining this end, whereby the wheel and clevis areconveniently adj nsted as to height and held seenrelyin their adjustedpositions by a simple and practicallyoperating device or attachment tothe plow, as will be hereinafter described,andsubsequently pointed outin the claim.

In the accompanying drawing, which represents aside view of a plow withmy at tachment applied thereto, A designates the plow, B the beamprovided at its rear end with the usual handles, G, all of which areofthe ordinary construction.

To the rear end of the plow-beam B is suitably fastened a segmentalnotched bar, a, with which engages a spring-latch consisting of a rod,D, held to a hand-lever, E, by means of lugs b, which are perforated orhave holes through which extends the rod. The lever E is pivoted at c tothe beam B, and the rod D is bent at its upper end to form a hook, d,for convenience of operating it, a spiral spring, 6. being coiled aroundthe rod D, and is located between the two lower ones of the flanges orlugs b.

To the lever E is connected one end of a rod, f, and the forward end inlike manner is conupright portion of a bracket, 9, secured to theplow-beam. To the bell-crank lever F is suit 1 Serial No. 259,240. (Nomodel.)

ably connected the usual clevis, h, and to the bracket 9 and bell-cranklever are connected, respectively, the arms 11k, to the lower ends ofwhich is jonrnaled the wheel G. The arms kone on each side of theplow-beam-are provided with lugs Z, so that when the arms are raised theclevis will be carried with them. \Vhen it is desired to raise the wheelG, the latch is raised to disengage it from the notched plate a, and bybringing the lever E in a direction toward the handles of the plow thewheel will be elevated through the intermediate connections, consistingof the rod f and bell-crank lever, also the arms 2' k. As will be seen,both the wheel and draft-clevis will be raised to change the depth ofthe furrow without the necessity of stopping the plow.

The above means, especially the bell-crank lever and the arm with itslugs, are considered of material importance in rendering the attachmenteffective and easily operated, and it should be understood that bracket9 and arms i and it are duplicated alike on each side of the plow-beam.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

The combination, with the plow-beam and the bracket 9, secured thereto,near the forward end thereof, of the bell-crank lever F, pivoted to saidbracket, the arm i, secured at one end to said bracket. the arm is,pivoted at one end to onearm ofsaid bell-crank, the wheel G, jonrnaledin the lower ends of said arms i and k, the connecting-rod f, pivoted tothe other arm of said bell-crank, and the operat ing-lever E, pivoted tothe beam and connected with said rod, substantially as shown anddescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ALBERT M. NASH.
